# Well, we don't want to get into the business of creating (and maintaining)
# the full set of autotools source files for the ASL. This approach tries to
# leverage makefile.u, which comes with ASL.
# To support VPATH builds, the strategy is to copy the sources to the build
# directory, build, and then erase the sources when we're done. Start by
# copying the sources.

# System-specific tweaks. On Solaris x86, we need to build fpsetprec.s
# (fpsetprec64.s for 64-bit builds). Add it to the dependency list for
# amplsolver.a. The 64-bit question here is how to reliably recognise a 64-bit
# build. For GCC, -m64 should do it. For Sun Studio, it's more difficult.
# Studio 12 and later recognises -m64. Earlier versions require
# -xarch=, where something can be any of generic64, native64, amd64,
# or amd64a (and perhaps others). So ... let's go out on a limb and hope that
# -xarch=*64* will not pick up anything it shouldn't. Force leading and
# trailing spaces in the string we're matching, in case the 64-bit flag is the
# only content in CFLAGS.
